Description

BACKGROUND AND SUMMARY OF THE INVENTION

The present invention relates to wall storage systems typically employed in open plan office spaces which enable the building occupant to custom design a floor plan to meet the specific needs of the occupant. In accordance with this invention, a unique wall system is provided which utilizes prefabricated and wholly self-contained modular base components and storage components which can be installed with minimum labor and installation cost, and which can be rearranged as desired with similar labor and cost benefits.

It is known to design open office floor plans utilizing so-called "systems furniture" which permits rearrangement and restructuring without the time consuming effort of tearing down and rebuilding the otherwise "permanent" walls. For example, it is known to utilize storage components as interior walls, where all such components have a standardized height, with a clerestory extending from the top of the storage wall to the ceiling. Such systems, however, have required on-site assembly and construction of most if not all components of the wall system. In addition, the system is not modularized so that replacement of any individual section of the wall system required time consuming dismantling and reconstruction, particularly since individual units shared adjacent side walls and horizontal members extended a considerable length along the wall system.

In accordance with the present invention, a factory constructed set of modular elements, wholly self-contained, are provided which create a built-in appearance, but which allow for minimum on-site installation labor and hence cost. In addition, the wall system in accordance with the present invention permits subsequent changes in configuration with similar savings in labor and cost.

It is therefore a principal feature of the present invention that the wall system comprise modular base components for supporting a like of modular storage components, each being self-contained and structurally self-sufficient.

It is another feature of the present invention to permit the installation and reconfiguration of the modular wall system independent of the electrical installation. In other words, the modular base components allow a full modular electrical and electronic office wiring program to pass therethrough independent of any installation, removal or replacement of one or more modular storage components. Accordingly, the system in accordance with this invention allows replacement of individual storage components without replacement of the associated base components, and therefore without rewiring or interruption of electrical service, and/or the need for the services of electricians.

It is another feature of the invention to provide modular storage components which include hang-on panels on the "back" side of the storage components for an attractive built-in appearance in those instances where the components are visible from the front or back.

It is another feature of the present invention to provide a set of modular storage components for a built-in configuration which permits the utilization of clerestory elements which complete the floor-to-ceiling appearance.

It is another feature of the present invention to provide a factory constructed set of modular base and storage components which are built in accordance with standardized modular dimensions calculated to fit standard building lay-out grids.

In accordance with one exemplary embodiment of the invention, therefore, a modular base component is provided which includes four self-leveling leg structures secured to an upper supporting surface. Each base component also includes front and rear (optional) cover plates to provide an attractive appearance, but the otherwise out-of-view side areas of the base components are left open to permit the passage of communications and/or electrical cables beneath and along a plurality of adjacent base components. In an alternative embodiment, a welded frame construction is used for the base component.

In further accord with this exemplary embodiment of the invention, modular storage components are provided, each of which includes a bottom wall, a top wall, two side walls and a back wall. From this basic storage component structure, various unit configurations are possible including clothing storage units, adjustable shelf units, file drawer units, bookshelf units and the like, with or without forward facing access doors. In each case, however, the storage component is prefabricated at the factory as a structurally self-sufficient component, having substantially uniform exterior dimensions.

At the site of installation, the required number of base components are aligned in side-by-side relationship, with communications and/or electrical cables beneath the base components and extending through the open side areas thereof. Individual storage components are then mounted or stacked on the respective base components and are fastened to the base components and to adjacent storage components with a minimum number of fasteners. It is preferred that the fastener locations for all components be identical and symmetrical so that one or more individual components can be reversed i.e., rotated so that users on both sides of the storage wall may, if desired, have access to one or more of the storage components.

Dimensions for the base components and modular storage components are to be substantially uniform for any given project or installation, with exceptions noted. Initially, however, it will be helpful if the dimensions are first defined for purposes of this application. Depth refers to the front-to-back dimension width refers to the far left side-to-far right side dimension; and height refers to the top-to-bottom dimension.

Depth and height dimensions in preferred arrangements will be uniform for any given project or installation, but may change from project to project based on available space, etc. The width dimensions, however, may be uniform or may vary within a single installation, as will be explained in further detail herein.

In a preferred arrangement, the base components and storage components are located so as to be centered with respect to ceiling grids or tracks to permit the further installation of a clerestory between the storage components and the ceiling grid or track as desired.

Thus, in accordance with one exemplary embodiment of the invention, a modular storage wall system is provided which comprises a plurality of prefabricated modular base components having, for any given project or installation, substantially uniform depth and height dimensions, each base component including a plurality of support legs and a top surface for supporting a wall component thereon, the base components further being configured to permit passage of cables therethrough; a plurality of prefabricated modular storage components, also having substantially uniform depth and height dimensions, the depth and width dimensions of the storage components being substantially identical to the depth and width dimensions of the modular base components; and fastening means for releasably securing said storage components to an underlying base component and to adjacent storage components, such that any one of the storage components can be removed without disturbing any other of the storage components or any of the base components.

In another aspect of the invention, the modular storage base component is provided which includes a free-standing, rectangular base component for supporting a storage component, the base component comprising a rectangular top wall mounted on four, self-leveling legs located at four corners of the top wall; and a first removable front cover extending between forward facing surfaces of a first forward pair of the legs. A second removable rear cover extending between rearward facing surfaces of a second rearward pair of the legs may be utilized.

Additional objects and advantages of the present invention will become apparent from a detailed description of the invention which follows.

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 illustrates a partial floor plan for an office layout incorporating wall systems in accordance with this invention.

The building is divided into a number of office spaces, three of which are shown at 10, 12 and 14. Typically, similar office spaces would extend about the outer periphery of the building floor, with common areas, service areas (elevators, etc.) and special purpose rooms arranged in the interior space.

While the invention will be described below in the context of adjacent office spaces about the outer periphery of the building, it will be understood that virtually any interior, non-structural wall may comprise a modular, built-in storage wall system in accordance with this invention.

Theoffice space 10 is defined by anexterior building wall 16, a pair ofconventional side walls 18, 20 and afront wall 22. The latter wall is constructed in accordance with this invention. In fact, as is apparent from FIG. 1,wall 22 serves as the front wall foradjacent office spaces 12, 14, etc., with interruptions only at the location of thedoors 24 for each office.

It will be further appreciated that theconventional side walls 18 and 20 may be replaced by wall systems constructed in accordance with this invention. In addition, and as also shown in FIG. 1, theoffice space 14 is shown to have a "built-in" wall system 22' in accordance with the invention, installed along a portion of thewall 20. It will thus be appreciated that the wall system of this invention may be utilized in a number of different settings, including free standing, and in combination with an existing wall to thereby provide great flexibility in the design and layout of office space.

With reference also to FIGS. 2 and 4 through 6, thestorage wall 22 is constructed of a plurality of prefabricated,modular base components 28, arranged in side-by-side relationship, each supporting a prefabricated,modular storage component 30.

Referring particularly to FIGS. 4-6, eachbase component 28 includes a supportingsurface 32 which is preferably 3/4" standard Melamine-coated particle board, but other materials such as wood or steel can also be used. Foursteel leg structures 34 are fastened to the underside of the supportingsurface 32 by any suitable means. Preferred heights for the base components are 5.5 inches where the 3/4 inch Melamine particle board is used, or 4.5 inches where steel weldments are used as the supporting surface (see the description below of the welded frame construction shown in FIG. 7).

Each leg structure comprises a beam-like,open section 36, with aconventional leveling screw 38 threadably secured in the bottom of thesection 36.

The front side of the base is preferably covered by asteel base cover 40 which may be snapped or screwed into place, usingconventional fasteners 42. The rear side of the base may be similarly covered with another steel base cover 44 (see FIG. 4), although this may be omitted if the wall system backs up to a finished wall as shown in theoffice space 16 of FIG. 1.

The side areas of the base component, shown generally at 46, 48 in FIG. 5, remain open so that communications and/or other electrical cables, such as modular cable assemblies, can extend freely along and beneath the base components as will be explained more fully below. In this regard,front cover plates 40 may be provided with electrical outlet plates 50 (FIG. 5), as required, along the length of the wall system. It will be appreciated that the use of modular cables in this installation will obviate the need for electricians and result in lower installation cost.

Theupper surface 32 of the base component is also provided with a pair ofholes 52 which receive threaded bushings 54 (FIG. 4), which, in turn, are adapted to receivescrew fasteners 56 in order to secure an associatedstorage component 30 in a manner described below.

Thestorage components 30 may have a variety of configurations including aclothing storage unit 30A, a combination file/storage unit 30B, and a bookshelf/storage unit 30C (with or without doors). This invention, however, is not in any way limited to specific configurations for thestorage components 30, and those skilled in the art will readily appreciate that many other storage component configurations may be employed.

Whatever the unit configuration, the storage components have a number of common elements. For example, each component is constructed of abottom wall 58, atop wall 60, a pair ofside walls 62, 64 and aback wall 66. Each of these walls, with the exception of the back wall, is preferably constructed of 3/4 inch standard melamine-coated particle board. The back wall is preferably the same material but with a 3/8 inch thickness.

This basic five-sided structure is held together by fasteners such as screws, adhesives, or combinations of both.

With reference to FIGS. 3 and 4, it may be seen that theside walls 62 and 64 extend rearwardly beyond theback wall 66. The extended side wall portions are provided with a plurality of brackets carryingsteel pins 68 which enable adecorative panel 72 to be secured to the back of the component viabrackets 70 which "hang" on thepins 68.Panel 72 may have upholstery, wood veneer, or any other suitable material applied to the exposed side thereof. This arrangement provides a uniformly attractive appearance along the back of the wall system, and is used where both sides of the wall system are exposed, as in theoffice space 10.

For those applications where the wall system backs up to an existing wall, as inspace 14, a 3/4 inch back wall 66' will be secured directly to the rearward ends of theside walls 62, 64, and no additional fabric-backedpanel 72 is necessary.

Thepanel 72 comprises, in one exemplary embodiment, a 1/2 inch Micore™ 230 panel with any suitable upholstery or other material, e.g. wood veneer, secured by staples or other suitable fastening means to the back side thereof. Typically, thepanels 72 have widths of about 48 inches, so that they may overlap the components 30 (depending on component width dimensions) as best seen in FIG. 3.

From the standard box-like construction described above, thestorage components 30 may be finished in a variety of configurations as also noted above. For example, theclothing storage unit 30A is provided with astorage shelf 74 and abracket 76 for supporting clothes hangers, and a pair offront access doors 78, 80.

The file cabinet/storage unit 30B is provided in one exemplary embodiment, with fourfile drawers 82, twoadjustable shelves 84, and a pair ofaccess doors 86, 88 to access the shelves.

The bookshelf/storage unit 30C may include five (or as few or many as desired, given the size of the unit)adjustable shelves 90 and a pair ofaccess doors 92, 94.

It is important to note that each of themodular base components 28 and modular storage components 30 (in whatever particular unit configuration), is constructed and fully assembled as wholly self-contained and structurally self-sufficient components at the manufacturing plant. Moreover, the dimensions of all base components and storage components are standardized and designed for compatibility with conventional building lay-out grids. For example, in one embodiment of the invention, all of thebase components 28 andstorage components 30 may be approximately 32 inches in width, and approximately 20 inches in depth. Thebase components 28 may have a height of approximately 41/2 inches, while the storage components may have a height of approximately 80 inches. Alternatively, individual storage components could be made with 16 inch widths, a pair of such components being supported on asingle base component 30. Similarly, storage components can be constructed with heights less than 80 inches, but which are vertically stackable to reach a combined height of 80 inches.

Generally, as previously noted hereinabove, the base components and storage components will have substantially uniform height and depth dimensions for any given project or installation, but may vary from project to project. For example, where floor-to-ceiling height is somewhat less than standard, all of the storage components of a wall system may have a reduced height of about 78 inches. As another example, the depth of all of the base and storage components of a wall system might be increased to 22 or 24 inches where space is plentiful.

On the other hand, width dimensions of individual base and storage components within a given wall system may be the same, or may differ according to a standardized modular format calculated to permit various combinations of widths, the totality of which will fill a predetermined modular planning space.

For example, for a 6 foot wall section or planning module, width dimensions of 12, 18 or 24 inches may be used, for example, in any combination that will result in a 6 foot long wall section. If the planning module is 8 feet, storage module widths of 16, 32, 48 inches may be used. Width dimensions for other planning modules or wall section lengths may vary accordingly. The widths for the base components will, of course, vary with the widths of the storage components.

This scheme facilitates production of standardized modular components which can be selected for use in various combinations to provide the desired overall configuration for the wall system.

At the installation site, themodular base components 28 are installed along the desired wall location, preferably centered beneath a ceiling grid or track. Thebase components 28 need only be aligned in side-by-side relationship, since it is not necessary to secure the base components to either the floor or adjacent base components.

Thereafter, after the communications and/or electrical cables have been strung along the wall site, through the open-sided areas of theadjacent base components 28, themodular storage units 30, in whatever unit configuration and in whatever sequence is desired, are mounted directly in vertical alignment on the upper supportingsurfaces 32 of the base components. In other words, each base component supports one (or two) storage component, and there is no overlapping relationship therebetween.

Alternatively, because of the relatively wide space available for the cables, cable installation may be accomplished after installation of thestorage modules 30, but before installation of the basefront cover plates 40.

Adjacent storage components 30 are fastened together by four connectors, preferably 1/4-2D connector bolts 96, as shown in FIG. 3. As noted hereinabove, a single screw is utilized to fasten each storage modular 30 to itsrespective base component 28.

Because the fasteners are located identically and symmetrically for all components, individual components can be moved about, and even rotated 180° within the wall system, quickly and easily without concern for whether or not fasteners on adjacent components will "match up".

It will be appreciated that, depending on the building and floor plan lay-outs, an odd dimension, i.e., something less than 32 inches, may (but not necessarily) remain to be custom fit at one or the other ends of the wall system. This can be solved by on-site modification of one of the base and storage components to insure a customized, built-in appearance. In a preferred arrangement, however, any relatively small, odd space remaining in a given planning space will be filled in by "blank" fillers or spacers to minimize the need for extensive custom work and expense.

After assembly of the base and storage components, the installation may be additionally "finished" by the attachment of a clerestory between thestorage components 30 and the ceiling, as best seen in FIG. 4. To this end, asoffet assembly 98 may be installed including a forward facingvertical soffet member 100, and one or more sections ofhorizontal supports 102.Supports 102, which extend across more than onestorage component 30, are fastened to each storage component by twofasteners 104. One or more sections of, for example 1/4" laminatedclear glazing 106 are then secured between theceiling track 108 and one or more base blocks 110 attached to thesupports 102. Since ceiling heights may vary, and since the height of all of the base and storage components is standardized, the glazing panels may be easily custom fit to the difference in height between the top of the storage components and the particular ceiling grid or track.

It will be appreciated, of course, that any suitable material may be used as the clerestory. For example, veneer, stone, fabric-backed panels and the like may also be employed.

In the event a clerestory as above described is utilized, thepanel 72, may extend beyond the top wall of the storage component, to approximately the same extent assoffet 102 to thereby provide a uniform, attractive appearance, hiding thebase block 10 from view. Alternatively, soffetmembers 100 may be used on both front and back sides of the wall system.

With the above described arrangement, it will be appreciated that any individualmodular storage component 30 can be easily removed from any section of the wall system and replaced with a component having the same or different unit configuration. To do so, theback panel 72, if present, is removed and thebottom wall fasteners 56, top wall fasteners 104 (when a clerestory is installed) and the fourfasteners 96 on each side wall, are also removed. Thestorage component 30 is then slidably removed from thebase component 28. Replacement is achieved in a similar manner, reversing the above described steps.

Another exemplary embodiment of the base component is shown in FIG. 7. This modifiedbase component 112 is formed by two pair ofangles 114, 118 and 116, 120, arranged in a rectangular shape (e.g. 31 15/16 inches in width and 19 inches in depth), and welded together at the four corners thereof. The angles are preferably, but not necessarily 1×1×1/8 inch hot rolled structural steel.Holes 122, 124 are drilled at opposite locations inopposed angles 116, 120 for receiving fasteners (not shown) which secure at associatedstorage component 30 to thebase component 112 in the same manner as described hereinabove. It will be appreciated that the top surfaces of each of theangles 114, 116, 118 and 120 provide a supporting surface for the associatedstorage component 30.

Legs 126 are welded at each of the four corners of the rectangular-shaped base component, each leg being formed by a pair ofU-shaped angle members 128, 130 joined along aweld line 132. Each leg is also provided with a levelingscrew 38 as previously described. A front plate 40 (andrear plate 44 if desired) can be secured to the base component, also as previously described. All of the advantages of thebase component 28 accrue to this alternative embodiment, but this embodiment has the further advantage of a lower height, e.g., 4.5 inches, which is particularly useful with storage components having heights of about 80 inches.

The removal and replacement of one or more storage components is thus easily achieved with minimum labor, and without any disturbance of the communications and/or electrical cables extending along the floor, through the base components.

Moreover, it will be apparent that removal of the storage components, rearrangement of the base components, and reinstallation of the storage components is also easily achieved, facilitating a total redesign of the floor plan with minimal effort and cost.

In summary then, the present invention allows for the installation of a custom wall system having an attractive, built-in appearance with minimum labor and minimum installation costs. This is achieved through the use of prefabricated, wholly self-contained base and storage components having standardized dimensions as described herein. In addition, replacement of one or more storage components, or rearrangement of the entire wall system is also easily achieved with similar savings in labor and cost, and without any interruption of electrical service.

While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
